摘要：
Gray mold is one of the frequently-occurring postharvest diseases of blueberry, which seriously affects the storage quality. The effects of Botrytis cinerea on the postharvest quality and antioxidant system of 'Brilliant' blueberry were studied with the fruits treated with sterile water as the control. The results showed that the reactive oxygen species (ROS) accumulated rapidly, the activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glycopeptide reductase (GR) and the the contents of ascorbic acid and glutathione increased rapidly in the infected blueberry fruits. At the late storage stage, the activities of antioxidant enzymes and antioxidant level were decreased, and the insufficient scavenging capacity of ROS lead to excessive accumulation of ROS and destruction of cell membrane structure, which accelerates the ripening, softening, aging and decay of blueberries. © 2019, Editorial Office of Journal of CIFST.
